Begin completing the square.  Divide all terms by
2 the coefficient of the squared term: 

Divide each side by '2'.
-31.5 + 12x + x2 = 0

Move the constant term to the right:

Add '31.5' to each side of the equation.
-31.5 + 12x + 31.5 + x2 = 0 + 31.5

Reorder the terms:
-31.5 + 31.5 + 12x + x2 = 0 + 31.5

Combine like terms: -31.5 + 31.5 = 0.0
0.0 + 12x + x2 = 0 + 31.5
12x + x2 = 0 + 31.5

Combine like terms: 0 + 31.5 = 31.5
12x + x2 = 31.5

The x term is 12x.  Take half its coefficient (6).
Square it (36) and add it to both sides.

Add '36' to each side of the equation.
12x + 36 + x2 = 31.5 + 36

Reorder the terms:
36 + 12x + x2 = 31.5 + 36

Combine like terms: 31.5 + 36 = 67.5
36 + 12x + x2 = 67.5

Factor a perfect square on the left side:
(x + 6)(x + 6) = 67.5

Calculate the square root of the right side: 8.215838363

Break this problem into two subproblems by setting 
(x + 6) equal to 8.215838363 and -8.215838363.

Subproblem 1
x + 6 = 8.215838363

Simplifying
x + 6 = 8.215838363

Reorder the terms:
6 + x = 8.215838363

Solving
6 + x = 8.215838363

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-6' to each side of the equation.
6 + -6 + x = 8.215838363 + -6

Combine like terms: 6 + -6 = 0
0 + x = 8.215838363 + -6
x = 8.215838363 + -6

Combine like terms: 8.215838363 + -6 = 2.215838363
x = 2.215838363

Simplifying
x = 2.215838363

Subproblem 2
x + 6 = -8.215838363

Simplifying
x + 6 = -8.215838363

Reorder the terms:
6 + x = -8.215838363

Solving
6 + x = -8.215838363

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-6' to each side of the equation.
6 + -6 + x = -8.215838363 + -6

Combine like terms: 6 + -6 = 0
0 + x = -8.215838363 + -6
x = -8.215838363 + -6

Combine like terms: -8.215838363 + -6 = -14.215838363
x = -14.215838363

Simplifying
x = -14.215838363

Solution
The solution to the problem is based on the solutions
from the subproblems.
x = {2.215838363, -14.215838363}
